MOTOR-PLOW.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed February 24, 1917. Serial No. 150,675.

fication, reference being had thereinV to the j accompanying drawing.

This invention relates generally to improvements in plows and more particularly has reference to an improved motor plow.

The present invention has for its particular aim and object to provide a motor plow embodying novel driving means whereby the improved plow carrying main frame may be propelled forwardly and rearwardly over a field without necessitating turning of the frame, thereby facilitating the plowing of the field and saving considerable time and labor that is normally consumed in properly adjusting a plowing machine of the types at present in use.

It is an additional object of thisinvention to provide novel means for shifting the head or end wheels when the plow reaches the ends of a eld that is vbeing plowed, clutch means coperating with the head wheels, which serve as auxiliary driving wheels, for disconnecting them from the driving means during the shifting operation.

More particularly, the present invention embraces the construction of the improved fra-me having the adjustable plowing means on the respective ends thereof, improved lifting` means acting in conjunction with the plowing means for properly adjusting the plows during the operation of the machine.

Among the other aims and objects of the'l cated in the drawings.

present invention may be recited the provision of a machine of the character mentioned with a view to compactness, the construction of which is simple, the cost of production comparatively low and the efficiency i invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the iinproved plow.

Fig. 2 is a top plan thereof.

Fig. 3 is an end elevation.

Fig. l is a detail of one of the head wheels.

Fig. 5 is a detail of the driving means.

Fig. 6 is still another detail.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings I provide a main supporting frame including side bars 1 and 2 the latter being shorter than the former and connected thereto by means of transverse end bars 3. Braces l extend diagonally `from points intermediate the ends of side bar 2 and are connected adjacent the outer ends of the side bar 1 to increase the rigidity of these portions of the bar 1. Arches 5 carryingupstanding studs 6 on their intermediate portions, the latter being journaled in the outer ends of the bar 1 while axles 7 are journale'd in the outer ends of the arches. The head wheelsl 8 are carried by the axles 7 for supporting one side of the frame. Sprocket wheels 9 are carried on the inner projecting ends of the shaft 7 for a purpose that will presently appear.` The opposite side lof the frame is supported by the main wheel 10 carried by a shaft 11 the `respective ends of which are journaled in a bearing 12 carried by the under surface of the bar 2 at a point substantially intermediate the ends thereof and in an auxiliary side bar 13 the respective ends of which are connected adjacent they ends of the side barv 2 as indi- .Withfa view toward connecting the plowing means to the frame I employ two pairs or sets of gang plows 14 and 15, the beams 16 of whichare pivotally supported on the end bars 3 while the plow points 17 of the plows 14 and 15 are arranged upon opposite sides of the wheel 10, and extendv in opposite directions toward the respective ends of the frame as indicated in the drawings. In order to raise either set of the plows 14 and 15 I have pivotally mounted levers 18 in the frame theforked ends 19- of which have links 20 pivotally connected thereto, the outer ends of the links in turn being pivotally connected to' the beams ofk the plows adjacent the moldfboards thereof.

These levers may be held in adjusted posi-M tion with respect to the frame by meansA ofA pawls 21 slidably and resiliently mounted frame. A hand lever 23is pivoted to the outer end of each lever 18vv and isv connected to thepawlby means of a rod 24 for moving the pawl against the' tension of the* spring 25avhich` is arranged toI normally hold the pawl in engagement with one" of the teeth of the rack. I

For the purpose of driving the frame for* wardlyland rearwardly over the ground I haveprovided an improved' platform sup'- port 26 the legs 27 of which are connected to the transversely extending cross bars 28 on the frame. An engine 29 of any suitable type is mounted on the supporting platform 26 while a transmission gear casing' 30 is mounted on 'the platform so that the gears thereof, (not shown) lare arranged in oper'- able relation with the .engine shaft and actuated by a controlling lever 3l for imparting an. alternate rotary motion to the shaft 32.' A stub shaft 33 is journalerd on one side of the supporting platform and carriesja bevel gear 34 on the upper end thereof which meshes with the bevel gear 35 on the outer end of the shaft 82. Another bevel gear 36 is mounted on the lower end of the shaft 33 and meshesy with: a large `bevel gearv 37 mounted on the' inner end of a shaft 38,

which in turn isjournaled' at a Apoint sub'-A :stantially intermediate the ends of the side bar 2 and in the longitudinal `bar3`8 of the frame. A gear 3,9 is carried by therouter projecting end of the shaft 38 andxmeshes with another gear 40 carried by the axle 11 soA that upon starting of the engine and' the l adjusting of the gears in the transmission casing, the wheel 10 willv vbe ultimately driven in a corresponding direction owing tov this gearing mechanism. In order tovimparta corresponding motion to the head wheels'a shaft 41 is journaled transversely of the frame in the side bar 1 andthe longi-4 tudinal bar 38 thereof and carries a bevel gear 42 on one end whichmeshes withjthe bevel gear 36A on the shaft A33,.l Another gear Ll-is carried by the shaft adjacent the' opposite" end and at all times meshes with a simi# larly formed gear 44 loosely mounted on vanothershaft 45, the latter in turnl being` jour'- 'naled transversely of the frame and in spaced parallel relation withv the shaft 41. A' clutch member46 is carried one face ofthe loosely mounted gear44 -while a collar.

serves tov prevent sliding movement of this' `nother clutch member 48A is slidably mounted on a key 49 on the shaft andis adapted tobe moved into engagement with they clutch member 46 by ladjusting means 50; This adjusting means may be sa-idVv to consist of -a pivotallymounted bell crank lever 5l on the frame, the lower Y`forkedlend of which lever is arranged in a groove in the clutch member 48 as shown at 52 while' thetvlever 51 extends through a slot in the platform so as to position the upper' 'handleportionA 54in'p`roximity to the driver so as to permit of the shifting of the clutch members and thus' rotate the*v shaft 45when y desired,` Sprocket wheels 55 and' 56are car'- ried inAv spaced relationL on the shaft 45 while chains '57 and 58 are loosely trained vabout the respective sprocket wheels. and also about the'isprocket Wheels `9` andy as will be readilyapparent, when the clutch' members are in engagement with each other rotary'j movement will be transmitted from vthe shaft` 45- .to the axles 7 to consequently rotate the wheels al corresponding direction.

As intifmat'ech` means have been provided for shifting th'e'head wheels 8 and in`v accomplishing this. purposek worm wheels A59 are carriedby the' upper ends of the studs 6 while the worm wheels are arranged in mesh with'the worms 60 formed adjacent the inner ends ofy the steering rods 61 journaled inA bearings 62| adjacent the outer ends of thebar 1 and also in bearingsy 63 mounted on the frame. ySteering wheels 64 mounted on' the opposite" endsof the steering rods are respectively arranged above thed-rivers' or operators` supporting platforms 65 as indicated in the drawings.`

The operation of the present invention may' be reviewed as follows :i

Vf'kssuming that the partsV have been assem# bledin the manner described and it is de' sire'd` toplow'a field, theI plows 14 are prop# erly adjusted" iny the ground while the plowsV 15 are removed ,from .engagement with the groun'chthis operation being effected by adfjusting the hand levers 18. Theengne 291s now started inf the' usual manner subsequent tojadjusting the gears in the transmission' by the controlling.k l'everjlf This causes the' gear wheel 35 which meshes with the gear34 to'impart rotary motion to the shaft 33 and rotary motion is in turn imparted tov lthe kshaftBS` through the 4medium of theJ gears 86 and 37 carried respectively by the shafts 33`jand 38'. Inasmuchasthegear 39 meshes wi'thvthe' gear 40 on the axle 11 the middle traction wheel will be Vvrotated to move` the frame"v in the direction. in which the plofws lio 14A-point.. During thisoperation the shaft 41 isA rotated ,owing to the gear 42 carried thereby meshing with the gear 86 upon the shaft and likewise rotary motion is impartedfrom'the shaft 41 to the shaft`45,` Y when the clutch members and47 `are in engagement with each other, by the gears 43 and 44 carried respectively by the shafts 4l and 45. The rotation of the shaft 45 carrying the sprockets 55 and 56 about which are loosely trained the chains 57 and 58 causes the head traction wheels to be rotated since the chains are also trained about the gears 9 carried by the shafts? which in turn carry the said head traction wheels and rotate them in the direction corresponding to the direction of rotation of the wheel l0. l/Vhen the plow reaches one end of the field the hand actuating lever 54 is moved to withdraw the clutch member 48 from engagement with the member 46 to prevent rotary motion being transmitted to the head wheels. During this operation the plows 14 are raised and the plows 15 are lowered. Simultaneously with this operation the controlling levers are adjusted to reverse the rotation of the Wheel 10. The hand wheels 64 are now rotated to shift the plow frame and after the frame and the plows carried thereby are properly arranged in the ground, the clutch members are arranged in engagement with each other so that a reverse rotation will be imparted to the head traction wheels corresponding to the direction of rotation of the wheel 10. When the plow reaches the other end of the field this operation is repeated to permit of the plow to travel in a reverse direction.

It will be understood that the above den scription and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters-Patent, is

1. A motor plow including a frame, head wheels connected at the respective ends of one side of the frame, another wheel rotatably mounted 0n the other side of the frame approximately intermediate the ends thereof, plowing means mounted at the respective ends of the frame, means for adjusting the plowing means, propelling means, means for operably connecting the propelling mea'ns with the intermediate wheel, means for shifting the head wheels, means operably connected to the propelling means for rotating the head wheels, means for reversing the movement of the wheels, and clutch means for disconnecting the head wheels vfrom the propelling means while they are being shifted.

2.
